Aft vs. Center Cockpit
I will definitely check out some of the boats you mentioned. I am quite familiar with the Hallberg-Rassy, and that is a good boat, but the warf offers very little customization options. What I like about the Wauquiez is the way they are built, very solid, for instance, not many boats come with a waterproof bulkhead that garantees it will withstand a collision with a container. Sheerwater is nice, but inmho too few of them around to expect wide support.
I have heard the argument before about the glass area, as mentioned by Paul, but I wonder whether this really is an issue nowadays. After all, some pretty expensive yachts, such as Farr, Turner, Stellar, Northwind, etc come with large "glass" areas and also most cats have the same. Are they all going to break when hit by a wave?
